The following disclosure relates generally to popcorn machines and other food service machines having communication capabilities, and more particularly to popcorn machines and other food service machines having remote or network communication capabilities for providing information related to operational status, malfunctions or other errors, remote operation, and the like.
Popcorn machines for producing popped corn are used in a variety of locations, e.g., individual homes, concession stands, restaurants, theaters, retail locations and industrial food production facilities. These popcorn machines can include sensors and electronic controls to aid or automate portions of the popping process. The electronic controls can maintain a desired temperature, alert an operator to an operating parameter, indicate an error or malfunction, or provide other functions. Although the electronic controls can provide several advantages, the benefits of the automation and the indication do not extend beyond the location of the machine, and may not result in the desired response. For example, popcorn machines operated in theater concession stands are often staffed by young workers without the skills or knowledge to conduct maintenance or replace parts. Accordingly, a notification to an operator that a malfunction has occurred may result in a less than prompt response.
Additionally, the popping process in existing popcorn machines may include several steps that are amenable to automation but still benefit from operator interaction, thus requiring the operator to be present at the machine. For example, popping machines can include automated operation cycles that can produce popped corn with differing ingredients, e.g., sweetened popcorn, savory popcorn, salted popcorn, etc. The ingredients are selected by the operator prior to initiating an operation cycle or a series of operation cycles. If the operator wishes to change the ingredients for a subsequent cycle, she has to alter the ingredient selection at the machine, either manually or through a control panel. If the operator is unable to promptly return to the machine, this can delay the production of the popped corn.
Several of the embodiments described below include features or advantages that overcome the above limitations of existing popping machines. However, reference throughout this specification to features, advantages, or similar language does not imply that all of the features and advantages that may be realized with the present invention should be or are in any single embodiment of the invention. Rather, language referring to the features and advantages is understood to mean that a specific feature, advantage, or characteristic described in connection with an embodiment is included in at least one embodiment of the present invention. Thus, discussion of the features and advantages, and similar language, throughout this specification may, but do not necessarily, refer to the same embodiment.
Furthermore, the described features, advantages, and characteristics of the invention may be combined in any suitable manner in one or more embodiments. One skilled in the relevant art will recognize that the invention can be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments of the invention.
These features and advantages of the present invention will become more fully apparent from the following description, or may be learned by the practice of the invention as set forth hereinafter. In order that the advantages of the invention will be readily understood, a description of the invention will be rendered by reference to specific embodiments that are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered to be limiting of its scope, the invention will be described and explained with reference to the accompanying drawings.
